Serial 1IN o. 783,153.

To all whom it may concern Be it known that I, EDMUND Hiinow, a1 citizen of the United States, residing at;

Brooklyn, in the county of 'Kings and State of New York, have invented vnew and useful',

Improvements in Automobile-Clocks,l of

. I'of Fig. l0.

which the following is a specification.

The present invention relates to time movements and more particularly to such as are designed for motor vehicles.

The invention provides novel winding andi; setting mechanism for time movementsr` whereby keys and pendantsfmay be dispensed with, such winding and setting mechanism` embodying a ring which when turned in one direction sets the hands and when turned in the opposite direction winds the spring, only one of such mechanisms being in gear at a time, the other being automatically thrown out of gear.

The invention provides a mechanism em-` bodying concentric stems each being in-` eluded in a train of gearing, one of such stems being directly operated andthe other stem being indirectly operated by means of a ratchet connection wth the primary stem.

The invention consists of the novel fea-` tures, details of construction and vcombina` tion of parts, which hereinafter will be more particularly set forth, illustrated in the ac-` companying drawings, and pointed out in the appended claims.

Referring to the drawings, forming a part. of the specification, Figure l is a side View, of an automobile clock embodying the in-f vention. Fig. 2 is a view similar to Fig. 1,

showinnr the frameof casin in section. Fi D 3 is a section on the line 3--3 of Fig. 2. lFig. i is an edge view of the operating ring partly in section. Fig. 5 is a front view of the movement having a portion of the .framey and dial broken away. Fig. 6 is a view of l gear. Fig. 9 is la sectional view similar to Fig. 7, showing the relation of the parts rmore clearly. Fig. 10 is an end view of :the pendant, showing more clearly the ratchet yconnection between the concentric stems. Fig. 11 is a section on the line 11-11 Corresponding and like parts are referred `to in the .following description, and indifcated in all 'the views of the drawings, by

the same reference characters.

The frame or casing lfor supporting the movement is indicatedgenerally -by the letter A and comprises a base l and a shell 2, `the latter being inclined to the base so as to give the V.proper set to the movement when attached to the dash of a motor vehicle. An inner flange 3 project-ing from the inner wall ofthe shell near the `outer end thereof supports the movement, the latter being retained in place by meansof a spring 4, which is of circular outline, as shown most clearly in Fig. 3, and embraces the casecontaining the movement. An operating ring B is fitted within the outer `portion of the shell 2 and is rotatable therein and comprises angularly disposed flanges 5 `and 6, the flange 5 entering the outer end'of the shell 2 and having an annulargroove 7 in which the 'inner ends of screws 8 are received to hold the ring in place, such screws 8 being 'let into the threaded openings formed in the shell 2 .near its outerend. The inner 4edge ofthe flange 5 is yformed with teethS), which are adapted to mesh -w-ith teeth 110 upon the outer side of the crown or head of the main operating stem. The -flange 6 projects beyond opposite sides ofthe flange 5 so as to'overlap the end of the shell 2 and thecase of the `movement. The outer edge of the flange 6 is milled or otherwise roughened to enable a firm grip being obtained thereon when turning the ring either 'to wind the spring of the time movement or to set the hands thereof. The inner portion of the flange 6 is beveled so as to come close to the case of the movement and obtain a neat finish.

The time piece may be of any construction and is usually of the type corresponding with a watch and comprises a case and movement, the latter being of any make and arrangement within the case and comprising winding and setting mechanisms such as generally provided in pendant or stem windin and setting watches. The setting mechanism embodies a train of gearing including gear wheels and 10 and pinions 11 and 12, as shown most clearly in Fig. 5.

The winding mechanism embodies the barrel 13 having the usual toothed portion which is in mesh with a pinion 14, said pinion being arranged upon the inner side of the back plate 15 of the movement and being fast to one end of a shaft 16, the other end of said shaft being provided with a disk 17, which overlaps the contracted end of an opening 18 formed in an edge portion of the back plate 15. The pinion 14 and disk 17 embrace opposite sides of the plate 15, thereby holding the pinion 14 in proper position. A spring 19 secured at one end to the plate 15 has its opposite end arranged to press 4upon the pinion 14 to hold it in mesh with the toothed portion of the barrel 13 containing the spring by means of which the time movement is operated. I/Vhen the main stem is turned to the left or in an anti-clockwise direction the setting mechanism is actuated and the winding mechanism automatically thrown out of gear, the latter result being due to the tendency of the force exerted to move the pinion 14 away from the toothed portion of the barrel. WVhen the main stein is rotated to the right or in a clockwise direction the force expended serves to press the pinion 14 toward the barrel 13, thereby acting in conjunction with the spring 19 to hold the pinion 14 in mesh with the toothed portion of the barrel 13, whereby the spring is wound. The pinion 12 is secured to the outer end of a shaft 20, which is mounted in the front plate 21 of the movement. A pinion 22 fast to the inner end of the shaft 2O is adapted to mesh with a pinion 23 secured to the inner end of a shaft 24, which is arranged within the main stem 25. The two stems 24 and 25 have a concentric arrangement, the stem 24 being mounted within the stem 25 to rotate and to move longitudinally therein. A light spring 26 is mounted upon the inner end of the stem 24 and exerts an inward pressure thereon to normally hold the pinions or gear elements 22 and 23 in mesh. A pinion 27 is fast to the inner end of the main stem 25 and is in mesh with the teeth of the pinion 14. The stem 25 is provided at its outer end with a crown or head 28, which is externally toothed, as indicated at 10, to mesh with the teeth 9 of the operating ring. The outer end of the head or crown 28 is recessed and is formed with ratchet teeth 29 which are adapted to cooperate with the ends of a pin 30 secured in an opening formed transversely of the outer end of the stem 24.

When the stem 25 is turned to the left the ratchet teeth 29 engage the projecting ends of the pin 30 and cause both stems 25 and 24 to rotate together, thereby operating the setting mechanism. Upon rotating the stem 25 to the right or in a clockwise direction the ratchet teeth 29 ride under the projecting ends of the pin 30 and move the stem 24 outward, thereby throwing the pinion 23 out of mesh with the pinion 22, during which time the spring is wound. The stem 25 is operated by means of the ring B in the manner hereinbefore stated.

From the foregoing description, taken in connection with the accompanying drawings, the advantages of the construction and of the method of operation will be readily apparent to those skilled in the art to which the invention appertains, and while I have described the principle of operation of the invention, together with the device which I now consider to be the best embodiment thereof, I desire to have it understood that the device shown is merely illustrative, and that such changes may be made when desired as are within the scope of the claims appended hereto.

Having thus described the invention what is claimed as new, is:

1. In combination, a frame, a movement arranged within the frame and having a stem, gearing connecting such stem with the winding and setting mechanism, each of such mechanisms engaging with the stem when .the same is turned in one direction and slipping when the stem is turned in the opposite direction so that only one of such mechanisms may be actuated at a time, and an operating ring fitted to the supporting frame and in engagement with the stem of the movement and adapted when turned in one direction to operate the setting mechanism and when turned in the opposite direction to operate the winding mechanism.

2. In a time mechanism, the coinbinaton of concentric stems one of such stems being mounted to have a rotary movement only imparted thereto and the other stem being mounted to have both a rotary and longitudinal movement imparted thereto, gearing connecting the respective stems with the winding and setting mechanisms, and a ratchet mechanism between the two stems arranged to operate automatically to cause both to turn in one direction and to move the other longitudinally and throw the same out of action upon rotating the Estem in the opposite direction.

3. In a time mechanism, the combination of a. rotating` stem, a second stem mounted concentric with the first mentioned stem and respective stems with the winding and setting mechanism, ratchet teeth upon the In testimony whereof I affix my signature outer end of the first mentioned stem and in presence of two witnesses.
